[MB-64109] Recovery does not restore dangling Analytics collections

Product: Couchbase Server
Component: analytics-service
Issue Link: MB-64109
Affects Version(s): 7.2.x, 7.6.x
Fix Version(s): 7.2.7, 7.6.4

Summary

Disconnected Analytics collections (as a result of an issue) will not be automatically reconnected and will require manual reconnection.

Dangling analytics collections are not restored during recovery (e.g., global recovery). The collections will remain in a disconnected state until their link (or another on the same local bucket) is explicitly connected via a CONNECT LINK DML, UI equivalent, or on a collection map on the same bucket.

Symptoms 

• Analytics collections are stuck in a disconnected (amber) state.
• Disconnected Analytics collections are not automatically reconnected.

Triggers

• The issue may be triggered by https://jira.issues.couchbase.com/browse/MB-63488 which results in the Analytics collections becoming disconnected.

Verification

Check whether Analytics collections are stuck in an amber (disconnected) state, following an issue that causes the collections to be disconnected.

Workarounds

Manually reconnect the disconnected Analytics collections by running CONNECT LINK on all Local links on the affected buckets.
